Follow LX40 in real time

The aircraft appears below whenever it is airborne and inside receiver coverage. Its planned route is drawn between the two airports.

LX40 is not transmitting right now. It may be between rotations, on the ground, or out of receiver range - Check back near 13:10 at ZRH. The full map has the rest of the sky, and what is flying over me will name whatever is above you instead.

LX40 at a glance

  • The trip: 9,535 km (5,925 miles) from Zurich to Los Angeles, flying north-west.
  • How long: 12h 10m gate to gate. That is about 784 km/h on average, taxi time included.
  • Your watch: set it 8 hours back on arrival.
  • Window seat tip: the left (south-facing) side gets the sun on a daytime flight.
  • The plane: usually a Boeing 777-300ER. This route uses about 70% of how far it can fly.
  • When it goes: out of ZRH in midday, into LAX in the afternoon. It is an overnight, so most of the cabin will try to sleep.

LX40 route overview: ZRH to LAX

LX40 distance and great-circle path

LX40 covers 9,535 km, or 5,925 miles. That makes it an ultra-long-haul flight, near the limit of what most twinjets can fly non-stop. Of the 439 routes we track, it ranks 91 by distance.

The plane leaves Zurich heading north-west. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the ZRH-LAX route appears on a tracker map.

Why LX40 block time differs from cruise time

The schedule allows 12.2 hours from gate to gate. That works out to about 784 km/h. A Boeing 777-300ER cruises faster than that. The gap is taxi time, climbing, descending and holding.

Winds aloft shift the real flight time by up to an hour in either direction. See how timing changes the trip in our red-eye flight guide.

Can the Boeing 777-300ER comfortably fly LX40?

Not really. It uses about 70% of the Boeing 777-300ER's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Boeing 777-300ER.

What to know about LX40

  • Time change: you land 8 hours behind the time you left. That is enough to cause jet lag. Here is how pilots handle it.

LX40 activity in the past 7 days

Our database contains 7 observations of LX40 across 7 UTC dates in this window, most recently 2026-10-29. Those records contain 5 distinct transponder addresses.

The median recorded visibility was 724 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does LX40 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 777-300ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown9,535 km
AircraftBoeing 777-300ER
Fuel burn rate8.86 kg per km
Fuel burned84,471 kg
CO2, whole flight266.9 tonnes
Seats, typical layout365
Passengers carried303 at an 83% load factor
CO2 per passenger881 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 881 kg cabin average and a flat bed well above it.

Economy299 seats, 248 flown
639 kg CO2 per seat
Business55 seats, 46 flown
1,855 kg CO2 per seat
First11 seats, 9 flown
2,558 kg CO2 per seat

Taken whole, LX40 emits what 4,449 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 5,182 km, or 25,170 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at sectors of 10,199 km, 11,112 km and 13,334 km, all longer than this route, so the closest is held flat and the real figure is likely a little higher. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put LX40 against another flight.

The route and typical schedule are maintained reference data. Live ADS-B observations are evidence of receiver coverage, not proof of on-time performance. Always confirm the operating date and times with the airline.
